ROTARY ROLL-PAPER FEEDER FOR TWO-REVOLUTION CYLINDER PRESSES.

Application filed October 26, 1926.

The present invention relates to a rotary roll paper feeder for a two revolution cyl nder press and the purpose of the machine is to provide a mechanical feeding attachment for ordinary hand feed cylinder presses, and by means of which any grade of paper from news print to the higher grades of book or bond stock in roll form is automate cally cut and delivered to the feed guides of the press to which it is attached. This machine can be quickly removed from the press and when so removed, the press is restored to its former status and may be therefore fed by hand, with paper in sheet form and in the usual manner.

Another very important object of the invention lies in the provision of a device of this nature with an exceedingly simple construction, which is inexpensive to manufacture, durable, efiicient and reliable in operation, not likely to easily become out of order, adjustable, and otherwise we il adapted to the purpose for which it is designed.

ith the above and numerous other objects in view, as will appear the description proceeds, the invention resides in cer-v tain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings I Figure 1 is a side elevation of a machine embodying the features of my invention,

Fig. 2 is a top plan view thereof, 1

Fig. 3 is asection therethrough substantially on the line 3-3 of Fig. 1,

Fig. 4 is a perspective view of a portion of the rack bar.

Fig. 5 is a detail view taken substan tially on the line.5-5 of Fig. 3,

Fig. 6 is a detailed view of the structure for taking power from the shoo-fiy-rod Referring to the drawings in detail, it will be seen that the numeral 5 denotes a platform from the sides of which rise standards 6 having journaled therebetween rolls 7 and 8. Ratchets 9 and 10 are loosely mounted on the shafts 11 and 12 respectively of the rolls 7 and 8 respectively. Dogs or pivoted pawls 13 and 14 are mounted respectively on rolls 7 and 8 and engage the ratchets 9 and 10 respectively. Gears 15 and 16 are fixed respectively to ratchets 9 and 10 to rotate therewith. A rack bar Serial No. 144,329.

17 is movable between the gears 15 and 16 and is meshed therewith. This rack bar 17 has a tongue and groove slidable connection 18 witha frame 19 supported on the platform 5. A rocker arm 20 is pivoted as at 21 011 one end of the platform 5 and has a plurality of apertures 22. A link 23 has a pivotal connection 24 with one end of the rack bar 17 and is provided with a plurality of apertures 26. A bolt 27 isadapted to pierce one of the apertures 22 and one of the apertures 26 for pivotally engaging the link 23 ,with the rocker arm.

20 and thus said pivotal engagement between the link' and the arm may be varied piercing one of the apertures 22. As is I well known the rod'28 rocks thereby oscillating the arm 29 for reciprocating the connecting rod 30 thereby oscillating the rock arm 20, and reciprocating the link 23 to impart rectilinear motion to the rack bar 17. As the rack bar moves in one direction it will impart rotary motion to the rolls 7 and 8 but when it moves in the other direction these rolls will remain stationary since the ratchet will not engage the pawls but will merely slip past them. These rolls 7 and 8 only rotate in a direction to take paper from the roll of paper 33.

Uprights 34 are provided in their upper ends with slots 35 in which are mounted slides 36 pressed downwardly by springs 37 which may be tensioned as at 38. These slides 36 have mounted thereon a movable knife blade 39 associated with a fixed blade 40. Projections 41 are provided on the slides 36 and one of them has aroller 42 thereon. A ledge 43 extends longitudinally on one face of the rack bar 17 and has an inclined end 44 terminating in a parallel portion 45. An auxiliary ledge 46 has hinged thereto a ledge portion 47 which is normally held upwardly by spring means 48 so that this portion 47 forms a continuation of theledge 43.

Referring particularly to Fig. 1, when the llU ' rack bar 17 is moving toithe left it does not I 1 ment thereto.

impaitany motion to the rolls 7 'and8 but as it moves to the right it imparts moveits the rack bar in its movement to the right reaches the end of its stroke, it will be seen that the roll r 42 resting on the ledge "43 passes "over the. end thereof and drops off to the parallel portion 45. In so doing, this roller allows the springs 37 to expand and forcethe movable blade of the 5 cutting mechanism downwardly for severing the paperi The paper will be delivered along: the endless'conveying mechanism illustrated diagrammatically at 50 in the well known manner and operable in any suitable manner ironrthe printing press.

'Upon tlie'lett hand movementot the rack bar, the roller-Twill travel up the incline 44.

.swinging the portion ifu pwa rdly and raising the l rnifeagainst spring; pressure. I

A pressure bar 5lr,precedes the cutting blade in reaching the surface for the paper and holds same taut in rea er tokeep it from shrinking or "sagging. Thus, a sheet of paper isdra'wn from the roll 33, delivered to the feed guidesot thefpressiand out with each forwar(l',inotion of the rack 17, The

l eng thi or width of paperfaccording to the width ofroll paper-arsed, is determined on relativelpositions 11561923 and 30 in respect to arm 20 as will befqulte'apparent' An eq'ualizingshatt 52 has an arm 53 extending under" one projection 41' and an 1 arm 54 extending over the other projection so that the cuttlng bar 1s maintained in a horizontal {position 'du'ring' its upward and mammal motion, this shaft being journaled in suitable bearings 55 on the uprights 6.

It is thought that the construction, operation, and advantages or q this invention 1 will now be clearly understood without a more fdetai'led de'scription thereof. The 'present embodiment of the invention has been disclosed in 'detailjmerely' by'way of example since in actual practiceflit attains the features of advantage enumerated as desirable in the statement "of the inventionand the above description. It will be apparent that changes in the details of construction,

and in the combination and arrangement of parts maybe resorted to without departing from the sp rit or scope'of the invention as hereinafter claimed or sacrificing any or its advantages.
